# 身高体重换算器：厘米换算英尺英寸，千克换算英石

主题：单位换算器

A height in centimetres becomes feet and inches by dividing by 2.54 cm per inch, rounding to the nearest inch and splitting into feet of 12 inches. A body weight in kilograms becomes pounds by dividing by 0.45359237 kg per pound, and stones and pounds by rounding to the nearest pound and splitting into stones of 14 pounds.

The default, 180 cm and 75 kg, gives 5 ft 11 in (70.87 in) and 165.3 lb, or 11 st 11 lb. Typing 5 ft 11 in or 11 st 4 lb straight into the fields works the other way.

Both factors are exact by the 1959 international yard and pound agreement, so the only approximation is the rounding to whole inches and pounds, which carries upward: 71.85 in shows as 6 ft 0 in, not 5 ft 12 in.

## 计算示例

### 180 cm and 75 kg

- 高度: 180 cm
- Weight: 75 kg
- **Height in feet and inches: 5 ft 11 in**
- **Height in inches: 70.87 in**
- **Weight in pounds: 165.3 lb**
- **Weight in stones and pounds: 11 st 11 lb**
- 核验来源：180 / 2.54 = 70.866 in → 71 in = 5 ft 11 in; 75 / 0.45359237 = 165.347 lb = 11 st 11.35 lb (Python fractions)

### 5 ft 11 in and 11 st 4 lb

- 高度: 5 ft 11 in
- Weight: 11 st 4 lb
- **高度: 180.3 cm**
- **Weight: 71.67 kg**
- **Height in feet and inches: 5 ft 11 in**
- 核验来源：71 × 2.54 = 180.34 cm; 158 lb × 0.45359237 = 71.66759446 kg (NIST HB 44)

### Rounding carries to the next foot and stone

- 高度: 182.5 cm
- Weight: 13 st 13.6 lb
- **Height in feet and inches: 6 ft 0 in**
- **Weight in stones and pounds: 14 st 0 lb**
- 核验来源：182.5 / 2.54 = 71.85 in → 72 in = 6 ft 0 in; 13 st 13.6 lb = 195.6 lb → 196 lb = 14 st 0 lb

### Exactly 5 feet

- 高度: 152.4 cm
- Weight: 75 kg
- **Height in feet and inches: 5 ft 0 in**
- **Height in inches: 60.00 in**
- 核验来源：152.4 / 2.54 = 60 in exactly

## 常见问题

### How tall is 180 cm in feet and inches?

5 ft 11 in. 180 cm ÷ 2.54 = 70.87 in, which rounds to 71 in, and 71 in is 5 × 12 + 11. Six feet (72 in) is exactly 182.88 cm; with rounding to the nearest inch, any height from 181.61 cm (71.5 in) upward shows as 6 ft 0 in.

### 如何将英尺和英寸换算为厘米？

Turn the height into inches, then multiply by 2.54. 5 ft 11 in is 5 × 12 + 11 = 71 in, and 71 × 2.54 = 180.34 cm. The factor is exact: the 1959 international yard and pound agreement fixed the inch at 2.54 cm, so any error comes only from how many decimals you keep.

### How many pounds are in a stone?

14 pounds, so one stone is exactly 6.35029318 kg (14 × 0.45359237 kg). A weight of 11 st 4 lb is 158 lb, or 71.67 kg. The stone remains in customary use for body weight in the United Kingdom and Ireland, and for weigh-ins in boxing and horse racing there.

### What is 75 kg in stones and pounds?

11 st 11 lb. 75 kg ÷ 0.45359237 kg/lb = 165.35 lb, which rounds to 165 lb; 165 = 11 × 14 + 11, so the weight is 11 stone 11 pounds. In pounds alone it is 165.3 lb, and 12 stone (168 lb) would be 76.2 kg.

### “身高体重换算器：厘米换算英尺英寸，千克换算英石”有多准确？

准确性取决于输入值和方法的假设。十进制运算使用50位有效数字，但估算、数值方法和源数据的精度可能较低；显示时的舍入并不能消除这些限制。 已按独立来源核验的计算示例：4。 例如，“180 cm and 75 kg”根据180 / 2.54 = 70.866 in → 71 in = 5 ft 11 in; 75 / 0.45359237 = 165.347 lb = 11 st 11.35 lb (Python fractions)进行核验。
